The support pipe 13 is used to fix the suction cup 14 on the shell 12, and the support pipe 13 and the suction cup 14 are communicated. The polaroid is adsorbed by the suction cup matrix 100, which can disperse the force when grabbing the polaroid, and the polaroid is more evenly stressed. Moreover, the edge part of the polaroid can be adsorbed and grabbed, preventing the polaroid from sagging and breaking when the polaroid is bent beyond a certain limit. By dividing the suction cup matrix 100 into a first area 101, a second area 102, a third area 103, a fourth area 104 and a fifth area 105, the first area 101, the second area 102, the third area 103 and the fourth area 104 are L-shaped, and by closing the suction cups 14 on the first area 101, the second area 102, the third area 103 and the fourth area 104 in turn, the adsorption area of the suction cup 14 can be adjusted to adapt to different sizes of large polaroids for grabbing and loading. Figure 2

[0035] The connecting assembly 2 includes a first pipe 21, a second pipe 22, a third pipe 23, a fourth pipe 24, a fifth pipe 25 and a connecting pipe 26. The first pipe 21, the second pipe 22, the third pipe 23, the fourth pipe 24 and the fifth pipe 25 are respectively connected with the first fixed pipe 11. The first pipe 21, the second pipe 22, the third pipe 23, the fourth pipe 24 and the fifth pipe 25 are respectively connected with the support pipe 13 on the corresponding suction cup 14 of the first area 101, the second area 102, the third area 103, the fourth area 104 and the fifth area 105 through the connecting pipe 26.

[0036] In the preferred embodiment, the first pipe 21, the second pipe 22, the third pipe 23, the fourth pipe 24 and the fifth pipe 25 are the same structure, and are respectively communicated with the first fixed pipe 11. The first pipe 21, the second pipe 22, the third pipe 23, the fourth pipe 24 and the fifth pipe 25 are respectively communicated with the support pipe 13 on the corresponding suction cup 14 of the first area 101, the second area 102, the third area 103, the fourth area 104 and the fifth area 105 through the connecting pipe 26.

[0037] ​In use, the negative pressure pump is connected with the first fixed pipe 11, and the negative pressure suction force generated by the negative pressure pump acts on the first pipe 21, the second pipe 22, the third pipe 23, the fourth pipe 24 and the fifth pipe 25 through the first fixed pipe 11, and the first pipe 21, the second pipe 22, the third pipe 23, the fourth pipe 24 and the fifth pipe 25 act on the corresponding support pipes 13 and suction discs 14 in the first area 101, the second area 102, the third area 103, the fourth area 104 and the fifth area 105 through the connecting pipes 26 respectively, and the suction discs 14 can adsorb and grab the polarizing sheet below, and the polarizing sheet can be adsorbed by the suction disc matrix 100, the force during grabbing the polarizing sheet can be dispersed, the polarizing sheet is more uniform in stress, and the polarizing sheet can be adsorbed and grabbed near the edge part, preventing the polarizing sheet from sagging and causing the polarizing sheet to break when bending beyond a certain limit.

[0038] If the first pipe 21 is closed, the negative pressure suction force cannot act on the corresponding support pipe 13 and suction disc 14 in the first area 101 through the connecting pipe 26, at which time the suction disc 14 in the first area 101 stops working, and the negative pressure suction force in the first fixed pipe 11 can still act on the corresponding support pipe 13 and suction disc 14 in the second area 102, the third area 103, the fourth area 104 and the fifth area 105 through the second pipe 22, the third pipe 23, the fourth pipe 24 and the fifth pipe 25 respectively through the connecting pipe 26, and the suction disc 14 can adsorb and grab the polarizing sheet below, and the relatively small oversized polarizing sheet can be adsorbed and grabbed by closing the first pipe 21. If the second pipe 22 is closed, the suction disc 14 in the second area 102 can be closed, and the relatively smaller oversized polarizing sheet can be adsorbed and grabbed. By closing or opening the first pipe 21, the second pipe 22, the third pipe 23, the fourth pipe 24 and the fifth pipe 25, the working state of the suction disc 14 in the corresponding first area 101, second area 102, third area 103, fourth area 104 and fifth area 105 can be changed, so that the suction disc 14 stops working or starts working, which is convenient for grabbing and feeding the oversized polarizing sheet with different sizes.

[0039] Example 2

[0040] Reference Figures 1 to 14 This example is based on the previous example, and differs from the previous example in that.

[0041] It also includes a control component 3, which includes a control pipe 31, a cylinder 32, and a movable shaft 33. The first pipe 21, the second pipe 22, the third pipe 23, the fourth pipe 24, and the fifth pipe 25 have the same structure. Five control pipes 31 are provided corresponding to the first pipe 21, the second pipe 22, the third pipe 23, the fourth pipe 24, and the fifth pipe 25. The control pipes 31 are fixedly connected to the first pipe 21, the second pipe 22, the third pipe 23, the fourth pipe 24, and the fifth pipe 25 respectively. One end of the cylinder 32 is fixedly connected to the inner wall of the control pipe 31, and the other end of the cylinder 32 is fixedly connected to the movable shaft 33. The movable shaft 33 is slidably connected to the inner wall of the control pipe 31.

[0042] In this embodiment, the preferred embodiment is referred to... Figure 4 When cylinder 32 extends, it drives movable shaft 33 to move. When movable shaft 33 moves to the position of the fifth pipe 25, it can seal the fifth pipe 25. At this time, the negative pressure suction inside the fifth pipe 25 cannot act on the connecting pipe 26 corresponding to the fifth pipe 25. Similarly, when cylinder 32 in the control pipe 31 corresponding to the first pipe 21, second pipe 22, third pipe 23, and fourth pipe 24 extends, cylinder 32 drives movable shaft 33 to move. When movable shaft 33 moves to the corresponding position of the first pipe 21, second pipe 22, third pipe 23, and fourth pipe 24, it can also seal them respectively. During assembly, the control pipe 31 is aligned with... Figure 4 After cutting open the cross section shown, and completing the installation of cylinder 32 and movable shaft 33, the control tube 31 is then welded together.

[0043] Reference Figure 5 The inner wall of the housing 12 is fixedly connected to the support plate 121. The support tube 13 includes a fixed section 131, a telescopic section 132, and a movable section 133. One end of the fixed section 131 is fixedly connected to the top wall of the housing 12, and the other end of the fixed section 131 is fixedly connected to one end of the telescopic section 132. The outer wall of the fixed section 131 is fixedly connected to the support plate 121. The fixed section 131 is fixedly connected to the connecting tube 26. The other end of the telescopic section 132 is fixedly connected to one end of the movable section 133. The other end of the movable section 133 is fixedly connected to the suction cup 14, and the movable section 133 slides through the bottom wall of the housing 12.

[0044] In this preferred embodiment, the support plate 121 is used to fix the fixed section 131. When the movable section 133 slides downward through the bottom wall of the housing 12, the movable section 133 can drive the suction cup 14 to move, and the suction cup 14 extends downward. At this time, the suction cup 14 is closer to the polarizer being grasped, which makes it easier to grasp the polarizer. When the movable section 133 slides upward through the bottom wall of the housing 12, the movable section 133 can drive the suction cup 14 to move, and the suction cup 14 retracts upward to avoid blocking the polarizer being grasped.

[0045] ReferenceFigure 6 The top of the movable section 133 is fixedly connected to a fixing ring 15, the fixing ring 15 is fixedly connected to a movable tube 16, and the movable tube 16 has an inner cavity 161 inside. The inner wall of the inner cavity 161 is slidably connected to a movable ring 17, the movable ring 17 is fixedly connected to one end of a second fixed tube 18, the other end of the second fixed tube 18 is fixedly connected to a support plate 121, and the telescopic section 132 passes through the middle of the movable tube 16 and the second fixed tube 18.

[0046] Preferably, in this embodiment, the inner wall of the movable tube 16 can slide relative to the movable ring 17. When the movable tube 16 slides downward, it drives the movable segment 133 to slide downward through the bottom wall of the housing 12. The movable segment 133 can drive the suction cup 14 to move, and the suction cup 14 extends downward. At this time, the suction cup 14 is closer to the polarizer being grasped, making it easier to grasp the polarizer. When the movable tube 16 slides downward, and when it slides upward, it drives the movable segment 133 to slide upward through the bottom wall of the housing 12. The movable segment 133 can drive the suction cup 14 to move, and the suction cup 14 retracts upward to avoid blocking the polarizer being grasped.

[0047] Reference Figure 5 The movable tube 16 and the second fixed tube 18 are fitted with a first spring 181, and one end of the first spring 181 is fixedly connected to the support plate 121, and the other end of the first spring 181 is fixedly connected to the fixing ring 15. The movable tube 16 is connected to the top of the control tube 31 through the first guide tube 162.

[0048] In this preferred embodiment, the first spring 181 helps improve the stability of the movable ring 17 and the second fixed tube 18 during their telescopic movements. When air is pumped into the movable tube 16 through the first guide tube 162, the movable tube 16 and the second fixed tube 18 will extend.

[0049] Reference Figure 7 It also includes a current limiting component 4, which includes a fixed cylinder 41, a movable plate 42, a baffle 43, and a second spring 44. The fixed cylinder 41 is fixedly connected to the movable section 133, the movable plate 42 is slidably connected to the inner wall of the fixed cylinder 41, the baffle 43 is fixedly connected to the other end of the movable plate 42, one end of the second spring 44 is fixedly connected to the movable plate 42, and the other end of the second spring 44 is fixedly connected to the inner end wall of the fixed cylinder 41.

[0050] In this preferred embodiment, when the movable plate 42 moves, it can drive the baffle 43 to move, and when the baffle 43 moves... Figure 7When the plate is in the middle position, the movable section 133 can be sealed, preventing gas from passing through it. When adsorbing and grasping the polarizer, after the suction cup 14 holds the polarizer, the negative pressure pump continuously provides negative pressure suction to ensure a firm grip. At this time, the interior of the movable section 133 becomes a sealed space. When the suction force inside the movable section 133 exceeds the negative pressure suction force, which is greater than the tension of the second spring 44, the movable plate 42 moves towards... Figure 7 When the movable plate 42 moves to the left, it can drive the baffle 43 to move, sealing the interior of the movable section 133 and preventing excessive negative pressure inside the suction cup 14 from damaging the polarizer, thus protecting the polarizer. During assembly, along... Figure 7 The cross-section shown cuts open the fixed cylinder 41. After the components on the inner wall of the fixed cylinder 41 are assembled, the fixed cylinder 41 is welded together.

[0051] Reference Figure 7 and Figure 8 The inner wall of the fixed cylinder 41 is fixedly connected to the limiting plate 45, the top of the limiting plate 45 is slidably connected to the baffle 43, and the inner wall of the movable section 133 is provided with a first receiving groove 1331 corresponding to the baffle 43, and the inner wall of the first receiving groove 1331 is slidably connected to the baffle 43. The inner wall of the movable section 133 is fixedly connected to the first sealing ring 1332, and the first sealing ring 1332 is located below the baffle 43.

[0052] In this preferred embodiment, when the baffle 43 moves, the limiting plate 45, the baffle 43, and the inner wall of the fixing cylinder 41 form a relatively enclosed space. When adsorbing and grasping the polarizer, after the suction cup 14 holds the polarizer, the negative pressure pump continuously provides negative pressure suction. Once the negative pressure suction inside the movable section 133 exceeds the tension of the second spring 44, the movable plate 42 moves towards... Figure 7 Move to the left in the middle until it reaches the middle. Figure 8 At the position in the middle, the baffle 43 is inserted into the inner wall of the first receiving groove 1331. At this time, the baffle 43 seals the inside of the movable section 133 to prevent the negative pressure suction inside the suction cup 14 from being too large and causing damage to the polarizer.

[0053] Reference Figure 7 and Figure 8 The baffle 43 is provided with a second receiving groove 431. The inner wall of the second receiving groove 431 is slidably connected to a slider 432. A third spring 4321 is fixedly connected to one side of the slider 432. The other end of the third spring 4321 is fixedly connected to the inner end wall of the second receiving groove 431. A limiting post 4322 is fixedly connected to the inner end wall of the second receiving groove 431. A locking block 433 is fixedly connected to the other side of the slider 432. An inclined surface 4331 is provided on the locking block 433. A third receiving groove 1333 is provided on the inner wall of the first receiving groove 1331 corresponding to the locking block 433. A second sealing ring 434 is fixedly connected to the inner wall of the second receiving groove 431. The locking block 433 is slidably connected inside the second sealing ring 434.

[0054] In this preferred embodiment, after the baffle 43 is inserted into the inner wall of the first receiving groove 1331, when the locking block 433 moves to the position of the third receiving groove 1333, under the action of the elastic force of the third spring 4321, the slider 432 is pushed towards... Figure 8 The slider 432 moves upward, causing the locking block 433 to move. After the locking block 433 is inserted into the third receiving groove 1333, the baffle 43 cannot be pulled out of the first receiving groove 1331. The inclined surface 4331 facilitates the insertion of the baffle 43 into the first receiving groove 1331. The limiting post 4322 can prevent the third spring 4321 from being over-compressed.

[0055] Reference Figure 4 , Figures 7 to 10 The interior of the second receiving groove 431 between the slider 432 and the second sealing ring 434 is connected to the interior of the fixed cylinder 41 between the movable plate 42 and the limiting plate 45 through the second guide tube 435, and the interior of the fixed cylinder 41 between the movable plate 42 and the limiting plate 45 is connected to the bottom of the control tube 31 through the third guide tube 436.

[0056] In this embodiment, the preferred embodiment is referred to... Figure 4 When cylinder 32 extends, it drives movable shaft 33 to move. When movable shaft 33 moves to the position of the fifth pipe 25, it can seal the fifth pipe 25. At this time, cylinder 32 continues to extend, and movable shaft 33 compresses the air at the bottom of control pipe 31. The air pressure acts on the inside of fixed cylinder 41 between movable plate 42 and limit plate 45 through third guide pipe 436, and then acts on the inside of second receiving groove 431 between slider 432 and second sealing ring 434 through second guide pipe 435. At this time, under the action of air pressure, slider 432 moves towards... Figure 8 Slide the lower part of the middle to release the locking of the block 433 to the baffle 43, at which point the baffle 43 can be pulled out from the first receiving groove 1331.

[0057] Reference Figures 12 to 14 It also includes an indicator component 5, which includes a first contact plate 51, a second contact plate 52, a power supply 53, and an indicator light 54. The first contact plate 51 is fixedly connected to the inner wall of the first receiving groove 1331, the second contact plate 52 is provided corresponding to the first contact plate 51, the second contact plate 52 is fixedly connected to the baffle 43, and the inner wall size of the third receiving groove 1333 is larger than that of the locking block 433, so the locking block 433 can move in the third receiving groove 1333. The first contact plate 51, the second contact plate 52, the power supply 53, and the indicator light 54 are connected in series.

[0058] In this preferred embodiment, when adsorbing and grasping the polarizer, after the suction cup 14 picks up the polarizer, the negative pressure pump continuously provides negative pressure suction. Once the negative pressure suction inside the movable section 133 exceeds the tension of the second spring 44, the movable plate 42 moves towards... Figure 7Move to the left in the middle until it reaches the middle. Figure 8 In the middle position, the baffle 43 is inserted into the inner wall of the first receiving groove 1331. At this time, the first contact plate 51 and the second contact plate 52 are in contact, and the first contact plate 51, the second contact plate 52, the power supply 53 and the indicator light 54 form a passage. The indicator light 54 lights up, indicating that the baffle 43 is inserted into the inner wall of the first receiving groove 1331, the movable section 133 is closed, and the baffle 43 is not loose. When the second contact plate 52 and the first contact plate 51 are disengaged, the indicator light 54 goes out, indicating that the baffle 43 is not fully inserted into the inner wall of the first receiving groove 1331. The power supply 53 and the indicator light 54 can be fixedly installed on the outer wall of the movable section 133. The power supply 53 is preferably an existing battery.

[0059] In use, if the size of the polarizer only requires the corresponding suction cups 14 on the second region 102, third region 103, fourth region 104, and fifth region 105 to work, the cylinders 32 inside the control pipes 31 on the second pipe 22, third pipe 23, fourth pipe 24, and fifth pipe 25 retract. At this time, the position of the cylinders 32 is the working position, and the cylinders 32 drive the movable shaft 33 to move. The movable shaft 33 moves to... Figure 4 When the fifth pipe 25 is above the moving shaft 33, the moving shaft 33 will compress the air at the top of the control pipe 31 and pump the air into the moving pipe 16 through the first guide pipe 162. At this time, the moving pipe 16 slides downward. The moving pipe 16 drives the moving section 133 to slide downward through the bottom wall of the housing 12. The moving section 133 can drive the suction cup 14 to move. The suction cup 14 extends downward. At this time, the suction cup 14 is closer to the polarizer being grasped, which makes it easier to grasp the polarizer.

[0060] Simultaneously, the cylinder 32 inside the control tube 31 corresponding to the first pipe 21 in the first region 101 extends. When the cylinder 32 extends, it drives the movable shaft 33 to move. When the movable shaft 33 moves to the position of the first pipe 21, it can seal the first pipe 21. At this time, the negative pressure suction inside the first pipe 21 cannot act on the connecting pipe 26 corresponding to the fifth pipe 25. Furthermore, during the movement of the movable shaft 33, when the air inside the movable tube 16 is drawn through the first guide tube 162, the movable tube 16 slides upward. The movable tube 16 drives the movable section 133 to slide upward through the bottom wall of the housing 12. The movable section 133 can drive the suction cup 14 to move. The suction cup 14 retracts upward to prevent it from blocking the polarizer being grasped.

[0061] Similarly, when the cylinders 32 in the control pipes 31 corresponding to the first pipe 21, second pipe 22, third pipe 23, and fourth pipe 24 extend, the cylinders 32 drive the movable shaft 33 to move. When the movable shaft 33 moves to the corresponding positions of the first pipe 21, second pipe 22, third pipe 23, and fourth pipe 24, it can also close them respectively. By closing or opening the first pipe 21, second pipe 22, third pipe 23, fourth pipe 24, and fifth pipe 25, the working state of the suction cups 14 on the corresponding first area 101, second area 102, third area 103, fourth area 104, and fifth area 105 can be changed, causing the suction cups 14 to stop working or start working, which is convenient for gripping and feeding ultra-large polarizing films of different sizes.

[0062] At this time, the negative pressure pump is connected to the first fixed pipe 11. The negative pressure suction generated by the negative pressure pump acts on the first pipe 21, the second pipe 22, the third pipe 23, the fourth pipe 24, and the fifth pipe 25 through the first fixed pipe 11. Since the first pipe 21 is closed, the second pipe 22, the third pipe 23, the fourth pipe 24, and the fifth pipe 25 act on the support pipe 13 and the suction cup 14 on the corresponding second area 102, third area 103, fourth area 104, and fifth area 105 through the connecting pipe 26, respectively. The suction cup 14 can adsorb and grasp the polarizer below it. The negative pressure pump will continuously provide negative pressure suction. After the negative pressure suction inside the movable section 133 is greater than the tension of the second spring 44, the movable plate 42 moves towards... Figure 7 Move to the left in the middle until it reaches the middle. Figure 8 At the position in the middle, the baffle 43 is inserted into the inner wall of the first receiving groove 1331 to seal the inside of the movable section 133 and prevent the negative pressure suction inside the suction cup 14 from being too large and causing damage to the polarizer.

[0063] Simultaneously, after the baffle 43 is inserted into the inner wall of the first receiving groove 1331, under the action of the elastic force of the third spring 4321, it pushes the slider 432 towards... Figure 8 The slider 432 moves upward, causing the locking block 433 to move. After the locking block 433 is inserted into the third receiving groove 1333, the baffle 43 cannot be pulled out of the first receiving groove 1331. Since the limiting plate 45, the baffle 43 and the movable section 133 form a relatively closed space at this time, the space is under negative pressure, which can maintain the adsorption of the polarizer. At this time, the first contact plate 51 and the second contact plate 52 are in contact, and the first contact plate 51, the second contact plate 52, the power supply 53 and the indicator light 54 form a passage. The indicator light 54 lights up, indicating that the baffle 43 is inserted into the inner wall of the first receiving groove 1331, the movable section 133 is closed, and the baffle 43 is not loose, and the suction cup 14 adsorbs normally.

[0064] When all suction cups 14 are working normally, the negative pressure pump can be turned off to save energy. When the movable section 133 above the baffle 43 leaks air due to sealing issues, the air pressure inside the movable section 133 above the baffle 43 decreases. Under the pulling force of the second spring 44, the movable plate 42 moves towards... Figure 7 The right side of the moving plate 42 moves the baffle 43 and the second contact plate 52 (see reference). Figure 12 and Figure 13 When the second contact plate 52 and the first contact plate 51 are disengaged, the indicator light 54 goes out, indicating that the baffle 43 is not fully inserted into the inner wall of the first receiving groove 1331 and there is insufficient negative pressure suction. This can serve as a timely warning. The suction cup 14 also has insufficient negative pressure suction. At this time, the locking block 433 is still inserted into the third receiving groove 1333. The baffle 43 cannot be pulled out of the first receiving groove 1331 to prevent air from rushing in from the movable section 133 above the baffle 43 and the movable section 133 below the baffle 43, causing the suction cup 14 to lose negative pressure and lose its adsorption of the polarizer.

[0065] When the polarizer moves to the predetermined loading position, it needs to be lowered. The cylinders 32 inside the corresponding control pipes 31 on the second, third, fourth, and fifth pipes 22 and 25 extend. As the cylinders 32 extend, they drive the movable shaft 33 to move. When the movable shaft 33 moves to the position of the fifth pipe 25, it can seal the fifth pipe 25. At this time, the cylinders 32 continue to extend, and the movable shaft 33 compresses the air at the bottom of the control pipe 31. The air pressure acts through the third guide pipe 436 on the inside of the fixed cylinder 41 between the movable plate 42 and the limiting plate 45, and then through the second guide pipe 435 on the inside of the second receiving groove 431 between the slider 432 and the second sealing ring 434. Under the action of the air pressure, the slider 432 moves... Figure 8 Slide the lower part of the middle to release the locking of the latch 433 on the baffle 43. At this time, the baffle 43 can be pulled out from the first receiving groove 1331. Under the action of a force greater than that of the second spring 44, the baffle 43 moves to Figure 10 At the middle position, the control cylinder retracts to the working position, and the next polarizing film can be picked up and loaded.
